The name is both an English acronym-like description and a Japanese wordplay meaning harmony of notes or chord. ### Projektgeschichte WaoN dates back to at least the 1998-2007 copyright span shown in the older SourceForge help output, making it an early Unix-oriented open source attempt at automatic music transcription. Its author described the original motivation as wanting to pick up piano voicings from favorite recordings and not finding a functional Unix application for that purpose. The project lived on SourceForge before moving to GitHub. Version 0.10 on SourceForge improved result quality by cleaning up useless notes, and version 0.11, released from GitHub in August 2015, fixed a gWaoN audio-device initialization bug and applied an older MinGW patch, with Win32 binaries becoming available from that era. ### Wie es verwendet wird WaoN's native input is WAV and its native output is Standard MIDI File format 0. Users can pipe audio through stdin and MIDI through stdout, combine it with SoX for broader audio formats, or pipe output to TiMidity for immediate playback. Technically, WaoN belongs to the older FFT and signal-processing lineage of automatic music transcription rather than the modern deep-learning lineage. Ichiki later compared the old FFT-based WaoN approach with Google's Magenta transcription work, making the tool a small but interesting artifact in open source audio-to-MIDI history. ### Zeitleiste - 1998-2007: the SourceForge-era help output identifies Kengo Ichiki's original development and copyright period. - 2015-08-09: v0.10 and v0.11 were published as GitHub releases, with v0.11 described as the first release from GitHub. - 2016: Ichiki published a comparison between WaoN and Google Magenta's music transcription work, framing WaoN as an older FFT-based program. ### Related projects - WaoN presents itself as the inverse of TiMidity/TiMidity++, which synthesize audio from MIDI. It also shipped related utilities: `pv`, a phase vocoder for time stretching and pitch shifting, and `gwaon`, a graphical front end/visualizer. ### Quellen - - - - - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** waon - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - Nix - waon: normalized package name match | nixpkgs package indexes: pkgs/by-name/wa/waon/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Verwandte Links - [Source-control packages](https://pkg.so/de/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/de/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://pkg.so/de/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [libsndfile](https://pkg.so/de/brew/libsndfile/) - Runtime dependency declared by Homebrew. - [fftw](https://pkg.so/de/brew/fftw/) - Runtime dependency declared by Homebrew. - [pkgconf](https://pkg.so/de/brew/pkgconf/) - Build dependency declared by Homebrew. - [timidity](https://pkg.so/de/brew/timidity/) - Shares pkgdb curated category or tags: audio, cli, media, midi, music. - [alsa-lib](https://pkg.so/de/brew/alsa-lib/) - Shares pkgdb curated category or tags: audio, cli, media, midi. - [fluid-synth](https://pkg.so/de/brew/fluid-synth/) - Shares pkgdb curated category or tags: audio, cli, media, midi. - [jack](https://pkg.so/de/brew/jack/) - Shares pkgdb curated category or tags: audio, cli, media, midi. - [streamrip](https://pkg.so/de/brew/streamrip/) - Shares pkgdb curated category or tags: audio, cli, media, music. - [aubio](https://pkg.so/de/brew/aubio/) - Shares pkgdb curated category or tags: audio, cli, media, music. - [csound](https://pkg.so/de/brew/csound/) - Shares pkgdb curated category or tags: audio, cli, media, music. - [bandcamp-dl](https://pkg.so/de/brew/bandcamp-dl/) - Shares pkgdb curated category or tags: audio, cli, media, music. - [audacious](https://pkg.so/de/brew/audacious/) - Both packages work with overlapping file formats or content types.
